Should I get my daughter a Lexus IS C or an Infiniti G37?

You rich or what? A 16 year old is going to trash a few cars before learning to drive, especially with friends talking, texting, and playing music. I'd go with a Mitsubishi Lancer. They are safe, have room for friends and get good gas mileage. Sounds like she's spoiled already! Teach her to work for her money or she is going to drive some poor guy out of his mind.
